Inspection
for House Fly
Trace adults back to the breeding materials named above: barn and feedlot manure, dumpster areas, and yard waste. Confirm a source by finding maggots in the suspect material, and check entry points, since most fly problems trace to poor exclusion and sanitation. Track fly specks and resting clusters to gauge whether numbers fall after cleanup. Source: https://texasinsects.tamu.edu/house-fly/ Source: https://ipm.ucanr.edu/PMG/PESTNOTES/pn7457.html
